To make 9 using four 2s, you can use mathematical operations: ( (2 + 2 + 2) \times 2 - 2 ). This simplifies to ( 6 \times 2 - 2 = 12 - 2 = 10 ). However, to correctly achieve 9, you can use ( 2 \times 2 + 2 + 2 ), which gives ( 4 + 2 + 2 = 8 ), and then you can adjust with parentheses and operations to find a valid configuration. A simpler way is: ( (2 + 2) \times 2 + 2 ) which equals ( 4 \times 2 + 2 = 8 + 2 = 10 ), but for a precise answer, the adjustment of operations is crucial.

How do you make the number 9 with five 2s only?
You can make the number 9 using five 2s by adding them together like this: 2 + 2 + 2 + 2 + 2 = 10, then subtracting 2: 10 - 2 = 8, then dividing by the remaining 2: 8 ÷ 2 = 4, and finally adding two more 2s: 4 + 2 + 2 = 9.

Can you make 9 using only four 2s?
Yes
Use substitution to prove that 2s + 3squared is not equivalent to 5s?
if s is 2, 2s is 4. 3 squared is 9. 4 + 9 = 13. 13 / 5 = 2.6, which is not equal to 2.

How do you factor 4s2-9?
4s2 - 9 can be expressed by using the identity: a2 - b2 = (a-b)(a+b) Therefore, 4s2 - 9 = (2s)2 - 32 = (2s-3)(2s+3)
-4 plus 3 plus 2s 15?
If you mean: -4+3+2s = 15 then s = 8
What does 2s-4 equal?
2s-4 equals 2(s-2). You can find the answer by factoring two out of both numbers.
